OUT1, OUT2 and Time Delay

The LM5030 provides two alternating outputs, OUT1 and OUT2. The internal gate drivers can each sink 1.5A

peak each. The maximum duty cycle for each output is inherently limited to less than 50%. The typical deadtime

between the falling edge of one gate driver output and the rising edge of the other gate driver output is 135ns.

Thermal Protection

Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event the excessive

junction temperature. When activated, typically at 165 degrees Celsius, the controller is forced into a low power

reset state, disabling the output drivers and the bias regulator. This feature is provided to prevent catastrophic

failures from accidental device overheating.
